Gas Properties
Gases do not have a definite this
Boyles law says
pressure increases as volume decreases
A sample of helium occupies 1000L at 15C and 1 atm. the temperature changes to -6C and the pressure to 0.55 atm. What is the new volume?
1684 L
We say gases are this because the particles are far apart and can be squeezed closer together
what is compressible
Charles law says
volume increases as temp increases
A sample of oxygen gas occupies 400 mL at 20C and 98.65 kPa. the gas is warmed to 30C and occupies a volume of 425 mL. What is the new pressure?
95.9 kPa
what is decreases
50L
Three moles of a gas occupy 41 L at a pressure of 3 atm. What is the temp
1000K
You could do these three things to increase the pressure of a gas
what is increase temp, decrease volume, and add more particles
A sample of gas at 10C and 2 L is heated until it expands to 4L. What is the final temperature?
566K
Calculate the number of grams of N2 gas present in a 6.00L sample at 1.00 atm and 22C.
6.38 g
A real gas behaves like an idea gas under these conditions
what is high temp and low pressure
A sample of gas occupies 100 mL at 100C. The sample is heated to 200C. What is the new volume?
.1268 L
Determine the Celsius temperature of 2.49 mol of gas in a 1.0 L container at 143 kpa
-266C
